Method performed by user equipment, and user equipment

Abstract

According to the present invention, provided is a method performed by user equipment, characterized by including: determining a resource conflict caused by a resource reserved in SCI transmitted by other UE, and if one or more conflict information indication enabling conditions are satisfied, transmitting a physical sidelink feedback channel (PSFCH) associated with the SCI and carrying conflict indication information, wherein the one or more conflict information indication enabling conditions include: information configured in a higher layer protocol enables conflict information indication, and indication information in the SCI enables the conflict information indication.

1 . A method performed by a user equipment (UE) as a first UE which communicates with a second UE, the method comprising:
 receiving Sidelink Control Information (SCI) from the second UE;   determining a resource conflict based at least in part on a resource reserved in a resource pool by the SCI; and   transmitting a physical sidelink feedback channel (PSFCH) in the resource pool, the PSFCH carrying a conflict indication, wherein   conditions of transmitting the conflict indication to the second UE, in a case where the resource conflict is determined, include the following conditions:   a) the first UE is configured by a higher layer protocol to enable an inter-UE coordination function, and   b) the SCI transmitted by the second UE indicates enabling of the inter-UE coordination function for the second UE.   
     
     
         2 . A user equipment (UE), comprising:
 a processor; and   a memory storing instructions,   wherein the instructions, when run by the processor, cause the UE, as a first UE which communicates with a second UE, to:   receive Sidelink Control Information (SCI) from the second UE;   determine a resource conflict based at least in part on a resource reserved in a resource pool by the SCI; and   transmit a physical sidelink feedback channel (PSFCH) in the resource pool, the PSFCH carrying a conflict indication, wherein   conditions of transmitting the conflict indication to the second UE, in a case where the resource conflict is determined, include the following conditions:   a) the first UE is configured by a higher layer protocol to enable an inter-UE coordination function, and   b) the SCI transmitted by the second UE indicates enabling of the inter-UE coordination function for the second UE.   
     
     
         3 . A user equipment (UE), comprising:
 a processor; and   a memory storing instructions,   wherein the instructions, when run by the processor, cause the UE, as a second UE which communicates with a first UE, to:   transmit, to the first UE, Sidelink Control Information (SCI) which reserves a resource in a resource pool; and   receive, from the first UE, a physical sidelink feedback channel (PSFCH) in the resource pool, the PSFCH carrying a conflict indication, wherein   conditions of receiving the conflict indication from the first UE, in a case where the first UE determines a resource conflict based at least in part on the resource in the resource pool, include the following conditions:   a) an inter-UE coordination function is enabled by a by a higher layer protocol, and   b) the SCI transmitted by the second UE indicates enabling of the inter-UE coordination function for the second UE.
